1sna115411r0700 – mb4/6.l8

Why Choose the TE Connectivity 1SNA115411R0700 MB4/6.L8 Distribution Terminal Block?

The TE Connectivity 1SNA115411R0700 is an ENTRELEC MB4/6.L8 grey distribution terminal block assembly designed to simplify the distribution of electrical connections within industrial control panels, machinery and automation equipment. The assembly consists of eight interconnected 4 mm² terminal blocks, providing a ready-made distribution solution that reduces the need for separate bridging components.

The MB4/6.L8 uses proven screw-clamp connection technology and has a 6 mm terminal pitch. The MB4/6 distribution family is rated at 32 A IEC and supports a nominal 4 mm² conductor cross-section, making this eight-block assembly suitable for organised distribution of control, auxiliary and industrial electrical circuits.

With an overall width of 50.5 mm, an 8 kV impulse withstand voltage and compatibility with G32, TH35-7.5 and TH35-15 DIN rails, the 1SNA115411R0700 provides a compact and installation-friendly approach to multi-point distribution. Its grey insulating construction and modular DIN rail format make it well suited to both new panel builds and existing system upgrades.

Pre-Configured Distribution for Efficient Panel Wiring

Distribution terminal assemblies simplify circuits where one electrical potential needs to be made available across several connection points. Rather than installing individual terminals and adding separate cross-connections, the MB4/6.L8 provides eight factory-interconnected blocks in a single ready-to-install assembly, helping reduce installation time and maintain an orderly terminal strip.

The 4 mm² MB4/6 platform combines a compact 6 mm pitch with a 32 A IEC current rating. Its support for G32 and both common TH35 rail depths makes the 1SNA115411R0700 particularly flexible for control-panel construction, machinery, auxiliary distribution and industrial automation systems.

Typical Applications

• Industrial control and automation panels.
• Common-potential and auxiliary circuit distribution.
• Machine control and factory automation systems.
• Power and control cabinet terminal strips.
• Instrumentation and process-control wiring.
• OEM machinery and industrial electrical equipment.
